As you know, user-defined commands must start with an uppercase letter. Sometimes, one would want a command starting with a lowercase letter, just as predefined commands. You may use
:cnoreabbrev for that. See an example below.
Use sparingly (Vim's rule is there for a reason)!
" Save file with sudo command! -nargs=0 :WriteWithSudo :w !sudo tee % >/dev/null " Use :ww instead of :WriteWithSudo cnoreabbrev ww WriteWithSudo
